key had a Content Type of "text\xml". I changed it to "application/x-zip-compressed" and IE now downloads zip files correctly. I have XMLSpy 2010 installed and my theory is that the installation of XMLSpy caused this problem.

To fix it, run regedit.exe and navigate to the key listed above and change the Content Type to "application/x-zip-compressed" (remove the quotes).

I'm having a similar problem, and this seems to have fixed it for me with Internet Explorer 8, but not Chrome or Safari. Maybe those other browsers are using different heuristics for determining the file type.
